How about I turn to the classics for a moment? This is decidedly not fanfiction (although, who knows what inspired Goethe ...)
This is a classic, and it is poetry, and - beware! - it is in German!
Johann Wolfgang von Goethe - Der Zauberlehrling
Music: Lively Lumpsucker by Kevin MacLeod (filmmusic.io standard license)
